Hi Roman,
Thank you so much for taking the time to answer my question, I appreciate that.
Regarding your answer, please bear with me till I get everything clear please.
1- Config your search console with the languages of your site (create a sitemap for every language if you have a multilanguage website)
My comment: My website is Only in Spanish, I'm using Yoast SEO on my Wordpress site, I think this plugin generates sitmap automatically without me creating it manually. I hope I'm right. Please correct me if I'm wrong.
2- Add the right href lang tag to your site - https://mza.bundledseo.com/learn/seo/hreflang-tag
My comment: Do I need to do that if my website is only in Spanish Language? Should I add "href lang" in my internal linking between the pages?
3- And Never forget to add as many schemas as you can - http://schema.org/
My comment: I'm not familiar with schemas, I would really appreciate more details on this point if you can please. What exactly does it mean and how can I do it?
Thank you again for your help Roman.
Regards,
Wajdi
